Hi Charmaine...Oscars are monomorphic, meaning that male and female look the same. So, unless they spawn, you may never know LOL ... How many do you have? and do you have pics?? I just love these fish  |

Don't have any pics right now, but I will get you a few to look at soon.
I have 1 Albino Oscar, and I would like to get him a partner. What do you suggest??
Yes they are such cool fish and mine has a personality of it's own. I just love the way he greets me when I get home from work.

Question: Oscars
Oscars has no different sex exept size at the same age.
If in same sex, males are larger but albinos sometime don't have.

From cichlid-forum.com:
Quote:
Unfortunately, determining the gender of an Oscar based upon finnage, colouration, markings, behaviour or size are not very reliable.
The only reliable method of determining the gender of an Oscar, is by netting them out of the tank, and holding them still while examining their genital area with a bright light available. It does take some practice to tell the difference, but the male's spawning tube points back towards the tail, and is located just in front of the opening of the anus. The female on the other hand, has a spawning tube that is less pointed, and points straight down. The female's genital area gives the impression of two openings including the anus.

From oscarfishlover.com:
Quote:
Oscars are what we call monomorphic, meaning that male and female look the same. This means that you can't go to a shop and choose a male and a female like you can with other species of fish. Contrary to a few people's belief, you cannot tell the sex of an Oscar by the shape of its fins, the length of its body, or even it is colouring. You will normally only know the sex of your Oscars when they start laying eggs.
...
Only when Oscars start laying eggs will you know for sure that you have got a male and a female. The females egg tube is overall in the shape, not unlike the pointed end of an egg. The males sexual organ is pointed and looks rather like a thorn.

How big is your current oscar, and how long have you had it? One thing to consider is that if you've had it for a while, it could be aggressive towards any new oscar that it feels is "invading" its territory. That might only last a little while, given how large your tank is, but it's something to watch out for. |
